Description

  The present invention relates to a device for displaying flag flags such as a flag, a flag, and a flag, and more particularly to a display device capable of automatically lowering the flag flag displayed in a strong wind.

  Flags displayed for shrine festivals and various types of advertisements are often spaced apart from one side edge and the top edge of an inverted L-shaped wooden column with an arm at the tip of the pole. It was displayed in a state where the flag was completely fixed to the column by inserting the hanging string protruding from the front. After that, metal poles that are superior in durability and aesthetics have come to be used, and there have been proposals for the convenience of raising and lowering the flag and for preventing the flag from wrapping around the pole.

  For example, in the hoisting device according to Patent Document 1, the upper part of a pole standing on the ground can be rotated horizontally, and a horizontal arm is extended from the upper part so that the eaves flag rotates according to the wind direction. The hoist flag is lifted by winding up the hoisting rope inserted into the arm through the pulley, while the hoist flag is wound around the pole while preventing the hoist flag from being wrapped around the pole. It was configured to lower the flag.

  Further, for example, in the flag pole according to Patent Document 2, while further storing the rope for lifting operation in the pole, a connecting member is interposed in the middle of the rope, and the upper half and the lower half of the connecting member A structure has been proposed in which the flag does not wind no matter how many times the flag is rotated in one direction around the pole. The operation rope stored in the pole has the effect of not causing an unpleasant metal sound because it is not beaten by the wind and hitting the metal pole like the conventional rope Has been.

  Certainly, according to the conventional flag raising device, the flag can be lifted and lowered by the rope operation, but the flag is prevented from being wrapped around the pole by the wind, and in some cases, the rope is uncomfortable metal. Although we were able to evaluate the fact that the flag was always beautiful and fluttering in the wind by preventing it from making a noise, as a countermeasure against a fall accident due to a sudden gust of wind, etc. There was no.

  In addition, in the hoisting device according to the above-mentioned Patent Document 1, since the anchoring portion for temporarily fixing the rope after the hoisting flag is hoisted is provided at the lower part of the pawl, the hoisting flag rotates many times in the same direction Had the disadvantage that the rope would wrap around the pole, hindering the lifting operation. In this regard, the flag pole according to Patent Document 2 in which a connecting member is interposed in the middle of the rope does not cause the rope to be wound no matter how many times it rotates in the same direction. There is also a new drawback that maintenance and the like are complicated due to the storage in the storage.

  However, in the present invention, while taking advantage of the characteristics of the conventional flag display device that can change the direction of the flag according to the change of the wind direction, it has a simple structure, such as when there is a strong wind or a sudden gust of wind. The main issue is to provide a flag raising device that can automatically lower the flag.

In order to solve the desired problem, in the flag lifting apparatus according to the present invention, a pole body standing from the ground, an arm extending horizontally and freely from the upper end of the pole body, and a ground side In the conventional flag display device, which is composed of an operation rope guided upward along the pole body and guided downward via the arm, and a hanging bar to which the upper edge of the flag flag is fixed, A heavy weight is inserted from the flag in order to allow the weight to rotate horizontally around the pole body, and one end suspended from the arm of the operation rope is connected to the middle position of the suspension bar. On the other hand, in the state where the other end is folded upward from the weight body and connected to the base end position on the pole body side of the hanging bar and the flag is raised, the operation rope is provided in the middle of the operation rope. Temporarily fixed to the locked part And so that arrangement, and the pole body uppermost, while providing the inverted enable wind receiving plate between an upright position and a horizontal position so as to be perpendicular to the arm, said the vicinity of the lower end of the wind receiving plate in an upright position The locking parts were connected with a descent rope.

  Therefore, the upper part of the flag flag in the hoisting state is attached to a suspension bar connected by an operation rope from an arm that is horizontally rotatable with respect to the pole body installed at the top of the pole body. The lower part of the flag is attached to an operation rope guided upward along the pole body from the weight body that can rotate horizontally with respect to the pole body, so no matter how much the flag flag that receives the wind changes its direction, The weight that is suspended by the arm and the operation rope that rotates horizontally with respect to the pole body also rotates horizontally following the movement of the flag, so even if it rotates several times in one direction, The flag does not wrap around the pole body. When the wind is strong, the wind receiving plate attached to the top of the pole falls to the maximum horizontal position, so that the locking part is operated by moving the tensioned descent rope upward by the falling of the wind receiving plate. Will be. When the locking portion is operated, the operation rope that was temporarily fixed is released, so that the flag is automatically lowered by its own weight.

  Here, the pole main body standing upright from the ground is not necessarily limited to the base portion embedded and fixed in the ground, but includes one temporarily installed in an open leg type. Such a temporary-type flag flag display device is expected to be demanded as a time-limited installation in an event or the like. Further, as the operation rope and the descent rope, a stainless steel wire rope is preferably used.

The weight of the weight body is determined in consideration of the weight of the flag flag, the suspension bar, the operation rope, and the like so as to balance in the display state of the flag flag. And as a latching | locking part provided in a weight body, it is a pin which moves up and down in parallel with a pole main body, and it can be comprised so that this pin may be inserted and inserted with respect to the eye part provided in the middle of the operation rope. If the descent rope is connected to the upper end of the pin, and the eye part of the operation rope is inserted into the lower end of the pin, the pin will move upward when the descent rope is pulled up by the overturning of the wind receiving plate. As a result, the pin is pulled out and the temporarily fixed state of the operation rope is canceled.

  In addition, the flag raising device according to the present invention employs an electrical automatic lowering mechanism that senses wind pressure instead of the mechanical automatic lowering mechanism that associates the wind receiving plate with the lowering rope and the locking portion. You can also. That is, a pole body standing upright from the ground, an arm extending horizontally from the upper end of the pole body, and guided upward from the ground side along the pole body and guided downward through the arm. In the conventional flag display device comprising a control rope and a hanging bar to which the upper edge of the flag flag is fixed, a motor and a power source are provided below the pole body and the total weight is larger than the flag flag. The weight set in this way is loosely fitted so that it can freely rotate horizontally, and an annular rope is stretched between the arm and the motor shaft so that it can be rotated forward and backward by motor drive, and one end hanging from the arm of the operation rope is suspended When the wind pressure sensor provided at the upper end of the pole body detects a wind pressure exceeding a predetermined threshold, the motor is driven to To lower the flag It can be.

  For example, as a wind pressure sensor, a Pitot tube type used as a speedometer for an aircraft or the like can be used. When wind pressure exceeding a predetermined threshold is press-fitted into the Pitot tube, the switch is turned on to start driving the motor. On the other hand, if all of the flag flags are lowered, the limit switch is operated to switch off and the motor drive can be stopped, so that the flag flag can be fully automatically triggered by strong winds. That is why. If a battery is used as the power source and electricity generated by sunlight is stored and used, the flag display device can be installed even in a place where it is difficult to supply power from the outside.

Furthermore, in the flag-lifting device using the motor drive, limit switches are provided at two positions of the weight body so as to be positioned on the left and right sides of the motor, while contacts serving as starting parts are provided at two positions of the annular rope. By configuring the motor so that the motor rotates forward or backward when these contacts touch the limit switch at the highest and lowest positions of the flag flag, it is possible to automate not only automatic flag lowering but also re-lifting. it can.

  Here, in either the mechanical or electric flag display device, a weight loosely fitted to the pole body is used in order to prevent the flag flag and the operation rope that winds from being wrapped around the pole body. While the body must be outside the pole body and held in a horizontally rotatable state, especially in mechanical devices, when the operating rope is released and the flag is lowered by its own weight In this case, the weight body also falls. If the weight falls to the ground, it will be difficult to raise the flag again and temporarily fix the operation rope to the locking part, so that the weight does not fall below a certain position. A stopper can be provided at a position below the weight body.

  In addition, if the flag is allowed to descend as far as possible, it will get entangled with the locking part, etc., which may hinder the operation when it is displayed again. In addition, by configuring the rope to pass through the guide hole drilled in a part of the collar, it is possible to restrict the flag from falling below a certain position.

  By the way, the arm is extended through bearings etc. so that its base part can rotate horizontally with the pole body, so the flag that flutters in the wind always adapts to the wind direction, but quickly changes due to the change in the wind direction. The arm can be provided with a vertical wind direction plate so that the wind receiving plate always reacts perpendicular to the wind direction.

  The upper edge of the flag is fixed to the suspension bar, but the suspension bar and the arm are only connected by an operating rope, so the arm follows the movement of the flag as the wind changes. For this purpose, the arm may be provided with a receiving portion for the hanging bar. As a specific example of the receiving portion, there is a member such as an inverted Y shape that is open at the bottom. For example, the receiving portion may be a simple one that is used upside down.

  In the flag raising device according to the present invention, if the operation rope is temporarily fixed to the locking portion provided on the weight body in the state where the flag is raised, when a wind with a strength exceeding the set threshold value is generated, When the wind receiving plate falls, the descending rope is pulled and the locking portion operates to release the temporary fixing of the operating rope, so that the flag is automatically lowered by its own weight. The flag at the time of hoisting is attached to an operation rope that connects between a horizontally rotatable arm and a horizontally rotatable weight body with respect to the pole body, so that it can freely rotate according to the wind direction. For this reason, there is no wrapping of the flag flag or operation rope.

  And the threshold of how strong the wind blows the flag is automatically adjusted by adjusting the size and angle of the wind receiving plate (how much the fall will cause the locking part to be activated) By doing so, it can be set easily.

Especially when a pin for vertically moving the engaging portion in parallel with the pole body top, only allow temporary fixation operation rope interpolate fit against the eye portion provided in the middle of the operation rope the pin On the other hand, it is possible to adopt a simple configuration in which the operation rope is released by being pulled out from the eye portion by the upward movement of the pin.

In addition, the flag raising device according to the present invention includes an electric automatic lowering mechanism triggered by wind pressure sensing, instead of a mechanical automatic lowering mechanism that operates the lowering rope and the locking portion by overturning the wind receiving plate. can do. In some cases, a timer operation can be added, and the motor can be automatically reversed after a predetermined time has elapsed (if it is still under strong wind, automatic descent will be performed again by sensing wind pressure) Also, the combination of the limit switch operation can be used to perform the descent operation and the re-lifting operation by forward or reverse rotation of the motor.

  And, by providing a stopper at a position below the weight body in the pole body, the weight body does not fall unnecessarily, and the temporary fixing operation of the operation rope to the locking portion provided on the weight body is facilitated. Can do.

  In addition, a hook is projected above the locking part of the weight body, and the rope passes through a guide hole drilled in a part of the hook so that the flag is below a certain position. By regulating so as not to descend, it is possible to prevent entanglement of the locking portion and the like.

  In addition, when a wind direction plate perpendicular to the arm is provided, or a receiving part for the suspension bar is provided, the arm and the flag are integrated to respond quickly to changes in the direction of the wind, while exceeding the threshold. It is possible to provide a flag display device that can react reliably to the flag and automatically lower the flag.

  DETAILED DESCRIPTION OF THE INVENTION Hereinafter, a flag flag display device according to the present invention will be described in detail according to the drawings. FIG. 1 is an overall view showing an example of a flag flag raising device according to the present invention. A pole body 1 standing from the ground using a concrete base K buried in the ground, and the pole body 1 An arm 2 that extends horizontally through a bearing or the like at the upper end, an operation rope 3 that is guided upward from the ground side along the pole body 1 and guided downward via the arm 2, and a flag 4 is similar to the hoisting device and the like according to the above-mentioned patent document in that the upper bar 4 is fastened, but the weight 6 is loosely fitted below the pole body 1. The point is greatly different from the conventional kite lifting device. The weight body 6 in this example is a double cylindrical body having a donut shape in cross section, and is configured to be filled with sand or the like so as to be heavier than the flag 4, and to rotate the pole body 1. It is loosely fitted as a shaft so that it can rotate horizontally.

  FIG. 2 is an enlarged view of an upper end portion of the flag flag display device shown in FIG. The operation rope 3 is formed by connecting the main rope 31 and the return rope 32 at the lower side, and the main rope 31 is temporarily fixed to the locking portion of the weight body 6 by providing an eye at the lower end. On the other hand, the tip is guided upward along the pole body 1 from the ground side, and goes downward from the pulley 10a attached to the base end of the arm 2 via the pulley 10b attached to the middle of the arm 2. After being guided, the suspension bar 5 is connected to an intermediate position. On the other hand, the return rope 32 is connected at the lower end to the eye part at the lower end of the main rope 31 and then folded back by a pulley attached to the weight body 6 and guided upward along the pole body 1. The suspension bar 5 is connected to the base end position on the pole body 1 side.

On the other hand, a wind receiving plate 8 that can be inverted between an upright position and a horizontal position is provided at the uppermost end of the pole body 1 so as to be orthogonal to the arm 2. More specifically, the wind-receiving plate 8 of this example formed in a disc shape is connected to one side of the front surface of the triangular horizontal plate 12 and a hinge (not shown because it is on the upper surface side). It is connected and is configured to be tiltable from an upright position shown in FIGS. 1 and 2 to a horizontal position along the horizontal plate 12. A descent rope 9 (see FIG. 2) having its tip fixed to the vicinity of the lower end of the wind receiving plate 8 in an upright position is bent and guided to the pole body 1 using a tubular material such as a flexible pipe as a sheath tube. It is guided down along. The positional relationship among these main rope 31, return rope 32, and descending rope 9 is shown in FIG.

  FIG. 4 is an enlarged view of the weight portion. The weight 6 that is entirely cylindrical and loosely fitted to the pole body 1 is suspended by the tension of the main rope 31 that is temporarily fixed to the locking portion 7 of the weight 6. The main body 1 is rotatable in the horizontal direction about the axis. A return rope 32 is connected to the lower end of the main rope 31, and the operation rope 3 is constituted by both ropes. The return rope 32 is folded upward with the pulley 10c as the lowermost end and connected to the base end portion of the suspension bar 5. The pulley 10c is configured such that its vertical position can be adjusted so that the suspension bar 5 is surely placed in the receiving portion 14 of the arm 2 when the flag 4 is displayed.

  A locking portion 7 is provided in a portion that is located at an upper portion of the weight body 6 and has a small diameter. 5 and 6 are both enlarged views of the locking portion 7. FIG. 5 shows a temporarily fixed state of the operation rope 3, and FIG. 6 shows a released state of the operation rope 3. The locking portion 7 of this example has a structure in which a pin 131 that moves up and down in parallel with the pole body 1 is slidably supported by a pin guide 132, and the pin 131 is attached to the eye portion 311 provided at the lower end of the main rope 31. The movement of the main rope 31 is regulated by insertion. The lowermost end of the lowering rope 9 is fixed to the upper end of the pin 131. When the lowering rope 9 rises, the pin 131 moves upward and is pulled out from the eye portion 311 of the main rope 31. The regulation will be lifted. An inverted U-shaped gate 133 that restricts the upward movement of the eye portion 311 is provided on the weight body 6 so that the eye portion 311 of the main rope 31 can be smoothly removed from the pin 131 that moves upward. Therefore, by inserting the eye part 311 of the main rope 31 from the outside of the gate 133 and then inserting the tip of the pin 131, the eye part is pressed by the gate 133 when the pin 131 moves upward. Thus, the movement of the pin 131 is prevented from following.

  Further, the eye portion 311 of the main rope 31 is bent into a smooth “<” shape so that the eye portion 311 does not get caught by other members at the time of ascending and descending. An eye part 321 provided at the tip is connected.

  In the eaves flag display device configured as described above, the main rope 31 having the lower end eye part 311 temporarily fixed to the engaging part 7 is tensioned with the suspension bar 5 via the arm 2. When the flag 4 tries to rotate with wind, the arm 2 and the weight body 6 also rotate horizontally around the pole body 1 as an axis. The operation rope 3 and the descent rope 9 composed of the main rope 31 and the return rope 32 are passed through the eyelet 41 which is drilled at an appropriate interval with respect to the long side on the pole body 1 side of the flag flag 4 together with the pole body 1. Since the flag 4 is rotated about the axis of the pole body 1, the pole body 1 rotates about the axis following the rotation of the flag 4. The pole body 1 is not always entangled.

  In order to more reliably prevent the flag 4 from being entangled with the pole body 1, as shown in FIG. 7, the eyelet 41 provided at the lower end of the flag body 4 on the pole body 1 side has another guide ring 42 and In contrast, it is preferable to provide a small guide ring 43 through which only the return rope 32 is inserted and to suspend the weight 44.

  As a result of the rectification of the wind by the flag 4 and the wind direction plate 11, the wind receiving plate 8 always faces upwind. When the strong wind blows, the wind receiving plate 8 attached via the hinge starts to tilt due to the wind pressure, and the descent rope 9 fixed to the lower end of the wind receiving plate 8 is eventually pulled up. The pin 131 moves upward while sliding on the pin guide 132 and is finally pulled out from the eye portion 311 of the main rope 31. Thus, when the main rope 31 is released from the temporarily fixed state, the flag 4 is lowered together with the suspension bar 5 by its own weight.

  It should be noted that how much strong wind the pin 131 should be pulled out, that is, how much strong wind blows the flag 4 automatically, mainly the size of the wind receiving plate 8 etc. For example, a turnbuckle 91 is provided in the middle of the descending rope 9 to adjust the length of the descending rope, thereby changing the tilting position of the wind receiving plate 8 (how much the wind receiving plate 8 is tilted). It is possible to easily perform fine adjustment even after installation by adjusting the length of the descent rope 9).

  When the flag 4 automatically descends, the return rope 32 that descends together does not get entangled with the flag 4 or the lowered flag 4 does not get messy around the locking part 7. A flange 15 projects from the upper end. A guide hole 151 is perforated in the flange portion 15, and the operation rope 3 and the descent rope 9 including the main rope 31 and the return rope 32 are inserted into the guide hole 151. While the flag 4 attached to the bar 5 is blocked by the collar 15 and stays on the collar 15, the return rope 32 is pulled downward from the guide hole 151 and then folded upward by the pulley 10c to re-open the guide hole 151. Since it comes out and rises smoothly, it does not get tangled in the vicinity of the locking portion 7.

  On the other hand, when hoisting the flag, if the main rope 31 connecting side of the return rope 32 constituting the operation rope 3 is pulled down by hand, the main rope 31 is pulled down following the return rope 32, and the pulley 10a and As a result of the suspension bar 5 being pulled up via the pulley 10b, the flag 4 is raised and displayed. When the suspension bar 5 comes into contact with the inverted Y-shaped receiving part 14 attached to the arm 2 so as to be opened downward, the flag 4 stops at the highest lifting state. Next, while inserting the eye portion 311 provided at the lower end of the main rope 31 from the outside of the gate 133, the lower pin 131 is inserted into the eye portion 311 while lowering the lifted pin 131, and the locking portion 7 is connected. When temporarily fixed, the weight body 6 is suspended by the tension action of the main rope 31 as described above, and is rotatable in the horizontal direction around the pole body 1 as an axis.

  FIG. 8 is a schematic diagram of a flag flag raising device when an electric automatic lowering mechanism that senses wind pressure is employed. In the pole body 1 erected from the ground, the arm 2 is extended from the upper end of the pole body 1 so that it can rotate horizontally. The operation rope 3 is guided upward from the ground side along the pole body 1 and two pulleys 10a, 10b is guided downward in the middle of the arm 2, and its tip is connected to an intermediate position of the suspension bar 5 to which the flag 4 is fixed. It is the same as the kite flag display device provided with the mechanical automatic lowering mechanism described above in that it is loosely fitted and freely rotatable.

  As a change point for adopting the electric automatic lowering mechanism, the electric motor M and the power source E are loaded on the weight body 6 and made endless with respect to the pulley P attached to the rotating shaft of the electric motor M. The lower side of the loop rope 16 was hung, while the upper side of the ring rope 16 was hung on the pulley 10d attached to the base end of the arm 2, and the lower end of the operation rope 3 was connected to the middle of the ring rope 16. For example, a wind pressure sensor 17 may be provided instead of the wind receiving plate.

Furthermore, in Nobori flag hoisted apparatus of this embodiment, together with the weight element 6 is provided with two limit switches S1, S2, the contacts A to the middle of the annular rope 16, the portion where the operation ropes 3 is connected to the annular rope 16 A contact B is provided so that the electric motor M is driven to rotate forward or reversely when each of the contacts contacts the limit switches S1 and S2. That is, the contact A contacts the limit switch S2 at the position where the flag 4 is lowered most, while the contact B contacts the limit switch S1 at the position where the hanging bar 5 of the flag 4 contacts the arm 2. It is set as follows.

  Since the weight body 6 is always suspended from the pulley 10d by the annular rope 16 hung on the pulley P of the electric motor M, the driving force of the electric motor M is reliably transmitted through the pulley P. . A wire rope is suitable as the annular rope 16, but it is also possible to use a chain after replacing the pulley P and the pulley 10d with sprockets.

  When the wind pressure sensor 17 detects a wind pressure exceeding a predetermined threshold value, the electric rope is energized in the electric motor M and the annular rope moves in the direction indicated by the arrow in FIG. Rotate 16 When the annular rope 16 moves, the operation rope 3 also rises, so that the flag 4 falls. When the flag 4 is lowered most, the contact A comes into contact with the limit switch S2, and the energization of the electric motor M is cut off, whereby the lowering operation of the flag 4 is completed.

  On the other hand, when re-energizing the electric motor M by setting a timer or the like, if the driving direction of the electric motor M is set to be reversed, the annular rope 16 is in a direction opposite to the direction indicated by the arrow in FIG. It will rotate to. As the contact B descends, the flag 4 rises, but when the contact B comes into contact with the limit switch S1 (at this time, the suspension bar 5 comes into contact with the receiving portion 14), the electric motor M The encumbrance operation of the flag 4 is completed at the same time as the power supply to the power is cut off.

  It is possible to introduce external power as the power source E for the electric motor M. However, while the power source E is a battery, a photovoltaic power generator is installed above the arm 2 to supply power to the battery. If planned, it is possible to provide a flag raising device that does not choose the environment of the installation location.

  FIG. 9 is a schematic diagram when the wind pressure sensor is a Pitot tube type. In the wind pressure sensor of this example, a total pressure is applied in the central pipe 171 and a static pressure is applied in the both side pipes 172. When wind is received from the right arrow direction, a sensor unit 173 such as a diaphragm is caused by the differential pressure. As a result of the rightward movement, the contact X and Y come into contact with each other to start energization of the electric motor M.

  FIG. 10 is a schematic diagram of another Pitot tube type used as a wind pressure sensor. A detection portion 176 having a large-diameter vertical cylinder is extended at the rear end of the bent tube body 175, and a wind pressure plate having a disk shape with respect to a support shaft 177 passing through the detection portion 176 vertically. 178 is pivotally supported. A contact X is provided on the outer edge of the wind pressure plate, and a contact Y is provided in the upper part of the detection unit 176. When the wind pressure plate 178 moves upward by the wind pressure introduced into the tube body 175, the contact X contacts the contact Y. Thus, the electric motor M is energized. Since an air amount adjustment hole 179 is provided below the normal position of the wind pressure plate 178 in the detection unit 176, the air amount adjustment hole 179 is introduced into the tube body 175 by adjusting the opening amount of the air amount adjustment hole 179. By adjusting the difference between the wind pressure to be applied and the pressure to push up the wind pressure plate 178, it is possible to adjust how much the wind pressure is energized.
